Question description

Early
tetrapods had a sprawling gait (like that of a lizard): As the right
front foot moved forward, the body twisted to the left and the left rib
cage and lung were compressed; the reverse occurred with the next step.
Normal breating, in which both lungs expanded equally with each breath,
was hindered during walking and prevented during running. Explain how
the origin of organisms such as dinosaurs, whose gait allowed them to
move without compressing their lungs, could have led to emergent
properties.
